城市形态信息图谱的理论框架与案例分析

Research on the Theoretic Method and Application of the Urban Form Information TUPU

本文主要对城市形态信息图谱的理论框架构建进行研究,并通过具体案例实践进行理论框架解析。首先,从城市形态的本体特征、层次结构、驱动机制三方面探讨城市形态的本体论,归纳总结城市形态本体;其次,从认识论角度对城市形态进行剖析,得出对于城市形态,应遵从系统论的认识;再次,在方法论的层面,通过对城市形态诸多方法进行探讨与比较,得出地学信息图谱方法是城市形态研究领域新的思维变革,地学信息图谱以其特有的"形数理"一体化的思维方式为城市形态的研究提供了的借鉴;然后,以中国222个城市为样本库,建立中国城市形态信息图谱,剖析应用城市形态信息图谱方法论进行城市形态研究的一般思维过程与技术流程,同时,构建中国城市形态信息图谱规划指导库,为城市规划提供指导;最后,总结城市形态信息图谱方法论的优势与不足。本研究尝试了将地学信息图谱方法引入城市规划领域,并通过案例证实了其实用性。

City is a complicated macro-system whose boundary geometry was formed by a number of interactional causes.Research methods on urban form can be summarized into two groups,i.e.quantitive approach and qualitative approach,but,there hasn＇t been a theoretical frame of urban form methodology which can be agree on till now.In this paper,the characteristics,hierarchical structure and driving mechanism of urban form are firstly studied,then,the epistemology of urban form is expounded,and,by comparing all the methodology on urban form research,the Geo-Info-TUPU methodology is considered to be the best one based on its special thinking modeling which integrates imagery thinking,mathematical thinking and deduce thinking together.Geo-Info-TUPU is a kind of methodology by which the spatial form and structure,the spatial and temporal variation rule of the earth system phenomenon are displayed after the process of the imagery thinking and the Abstract summary,and using the computer multi-dimensional and dynamic visualization technology.It supplies a new method in the urban form research field.After defining the conception of the urban form information TUPU,the normal thinking rule and the technique process are summarized and the theoretical frame of urban form information TUPU is built.Then,based on integrating the spatial data with the statistic figure,the urban form classification TUPU of China is built by using the indices of the compactness and fractal dimension to identify different categories,and,cities of China are roughly divided into six categories,i.e.centralized form,ribbon form,radioactive form,two cities form,ribbon group form and centralized group form.And then,the normal process of the Geo-Info-TUPU guiding city planning is put forward： calculating the quantitative indexes;making sure the urban form;analyzing the impact factors;finding out the city development period;and putting forward the suggestions of planning.At the end,the advantages and disadvantages of the urban form information TUPU are summarized.The advantages include vividness,accuracy and practicalness,whereas the disadvantage is that,the basic knowledge of the city should be know because the TUPU analysis is based on empirical hypothesis.The Geo-Info-TUPU supplies a new method in the urban form research field,and it can be used to diagnose the regular discipline and predict the future.
